NIANURE-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 791,964:, dated June 6,1905.

Application filed Octo r 1, 1904. Serial No. 226,860.

To all whom it may concern.-

Be it known that we, HARRY WELLER and J AMES B. Hown, citizens of theUnited States, residing at Marshall, in the county of Calhoun and Stateof Michigan, have invented new and useful Improvements inManure-Separators, of which the following is a specification.

It is the object of this invention to separate stable-manure from strawthat has been used in the stable and not yet worked into manure, withthe double purpose of drying the straw to such an extent that it may bereused as bedding and working it up into manure ready to be hauled intothe field.

The invention will clearly appear from the full description hereinaftergiven in connection with the annexed drawings, forming part of thisspecification, of which Figure 1 is a side elevation of the machinecomplete. Fig. 2 is a vertical longitudinal sectional view of the same.Fig. 3 is a plan view of the same. Fig. 4 is a transverse sec tionalview taken on the line 4: 4 of Fig. 3. Fig. 5 is a front view.

The same symbols of reference designate the same parts or features, asthe case maybe, wherever they occur.

In the drawings, 10 designates the frame of the machine, which may be ofwood or iron or partly of wood and partly of iron, as circumstances maysuggest or require. over, the height and other dimensions of the machinemay be suited to circumstances.

A hopper-like part 11 is formed at what may be termed the rear end ofthe machine, which has a gridded bottom formed from a series of slats12, arranged edgewise on a pair of double crank-shafts 13, which impartsto the said slats a walking motion, thoroughly shaking the griddedbottom of the hopper and causing the manure to fall through on an apron20, traveling in the direction indicated by the arrows, depositing themanure on a pile 15 at the rear end of the machine. The tendency of thewalking motion,of the slats forming the bottom of the hopper is to movethe straw forward upon a shaker or rack 19, movably supported inposition to receive the straw from the bottom of the hopper. The saidshaker comprises a series of slats and vibratory lift- More ing-fingerspivoted between the slats, which are operated with a tendency to shakethe finer foreign matters from the straw and move the latter forward onthe shaker. Under the forward part of the hopper there are slats 16,supported at their rear ends on the cross-rod 18, which slats inclineupward to the slats 40, forming the bottom of the shaker 41. From thehopper 11 the straw will be worked forward by the oscillating rack 19 tothe front end of the machine, where it will fall upon the floor in aquite clean condition. The fine manure worked out of the straw on itspassage forward by the shaker and fingers operating with it will fallthrough the slats forming the support for the straw and fall upon thehorizontal apron 20, by which it will be carried rearwardly and bedisposed of in the same way as the other manure spoken of.

Movement will be imparted to the operative parts of the machine from thedriving-Wheel 21 on a rod, or it may be a stub-shaft 22, which shaft maybe supported in suitable bearings on an upright 23 and be provided witha crank 24. The drive-wheel 21 may be a sprocketwheel and drive asprocket-chain 25, which passes about a sprocket-wheel 26 on the forwardshaft 18, thence up over a sprocketwheel 27 on the forward shaft 13,thence down and partially around the wheel 28 on the rearward shaft 18,thence up over a wheel 29 on the rearward shaft 13, thence down and incontact with the wheel 30 on the shaft 31, by which the apron 20 isdriven, and thence around idle pulleys or wheels 32 and 33 to the pointof starting.

Other means for operating the machine may be provided; but what we havedescribed will be found simple and efficient.

The roller 34: at the forward end of the machine about which the endlessbelt passes will be driven by the belt itself, as will be readilyunderstood.

As seen in Fig. 3, the whole upper part of the machine above the apronwill be openv and formed as a grid, so that the manure may at any pointfall through upon the apron, which carries it back on the pile 15, whilethe straw will be carried forward in practically cleaned condition, sothat it may be spread out and dried, if not already in that condition,and used again as bedding or in any other way to work it up into manure.

It is obvious that the machine can be manufactured at low cost and thatall the stablestraw of a barn of quite large size can be treated in avery short time daily.

The apron will be provided on its upper or out side with cross-slats tobe more effectual in carrying away the manure deposited on it.

Vhile we term this machine one for separating stable-straw, it will beunderstood as designed for separating manure from any straw orfodder-stalks in order to assist in working the straw and stalks intomanure by using it for bedding or tramping it by cattle into manure inthe barn-yard and straw-shed.

What we claim is- The combination of a frame formed at one end as areceiving-hopper, a bottom for separating and loosening the straw &c.,and feeding it forward, comprising a pair of correspondinglydouble-cranked shafts, and slats mounted on and receiving walking motionfrom said shafts, a shaker movably supported in position to receive thestraw from said bottom, comprisingslats and vibratory lifting-fingerspivoted between the slats; means for reciprocating the shakervandvibrating the fingets, and ahorizontal traveling apron extending beneathsaid bottom and shaker to receive the finer matters and deliver them atthe end opposite to the straw-discharge.

In testimony whereof we afiix our signatures in presence of twosubscribing witnesses.
